of Cincinnati, Hamilton county, State of Ohio,`

have inventedl a certain new'nand useful'Hub and Axle-Bearing; and lI 'do declare that the following is a description thereof sufficiently clear, full, and exact to enable others skilledv in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the referencenumerals marked thereon, which form also a part of this specification.

This invention relates to improvements in hubs and axle-bearings 5 and it consists of certain new and improved means, as hereinafter described, whereby a hub is held in position on an axle, the object and corresponding construction of these means being such as to obviate and reduce as much as possiblethe friction between rotating and stationary partsthat is, in particular between those parts and surfaces of the hub which engage en'dwise and come in contact with opposite surfaces and which hold the hub in position.

Subsidiary features of my invention relate to details of construction in general and of the means whereby the axle-bearing is rendered dust-proof.

In the following specilication, and particularly pointed out in the claims, is found a full description of the invention, together with its operation, parts, and construction, which latter is also illustrated in the accompanyingdrawings, in whichn Figure 1 is a central longitudinal section of a hub mounted uponian axle-journal and showinga bearingconstructed in a manner as contemplated by my j invention. Fig. 2 shows an end view ofl the hub with such parts which confine itin position on the axle` journal removed. Fig. 3 shows the discon-` nected ball-bearing nutwhich holds the hub in position on the axle-journal. Fig. 4 shows the removed outer ball-bearing'socket and dust-cap combined,- one nhalf of the figure showing same as it appears on the outside of the hub, the other as itappears inside; and Fig. 5 is a rearview of the hub and axle-bearing, the axle being shown in sectionand parts of the hub broken away.

In the drawings, 8 indicates the axle-jourmitted to `hub and axle-journal through a duct 12,closed lnal, which maybe straight or tapering, as shown. 9 is the sleeve or boxofthe wooden hub 11, of which it forms acomponent part and is shaped and sized yto fit the aforesaid journal. In an all-metal hub this box would of course not be required. Lubricant is adthe contacting bearing-surfaces of by a screw-plug 13, and distributed throughout the bearing by means of a spirally-disposed groove 14,cut into the bore of the sleeve. This latter is held on the axle-journal by means of a stationary nut 15, mounted on the outer threaded end of the axle and occupying a recess in the outer end `of the hub, which recess is obtained by enlarging the bore of the ,latter thereat. To reduce, the friction between the stationary surfaces of this nut which engage thefmoving surfaces opposite it within the recess at the outer end of the hub, I interpose balls 16 -thereat, whichV by preference are carried by this nut and on that side thereof which, is opposite the end of the hub. Asto number these ballsv are so limitedthat they do not toucheachother, for which purpose each is contained in a separate socket 17 provided forit. To hold these balls in their respective positionson nut 15 and to permit also of adjusting and renewing the surface of the nut against which these balls wear, they are inclosed and held each within aA bearing contained in this nut andV consisting of two separable shells or sections-- an inner one, 18, andl an outer one, 19-both held within sockets 17'4 of the nut by means of a screw connection, so as to form rcm0vable bearingsor holders for these balls. For such purpose they are provided with means, like socket-holes 21, to receive a requisite tool or spannen-wrench. Packing 22 may be interposed between these two sections. The outer or top section 19 has an opening through which apart of theinclosed ball projects for the purposeof permitting it to engage and bear against the opposite surface on the hub. This surface is represented by a flat ring 23,

on A,and around which thesev balls travel, kand which ring is preferably removably secured to the sleeve `of the hub in order to permit its independent renewal in case of wear, thereby obviating replacement of an entire hub. This ringis so attached, preferably by means of a screw connection,

to the end of the sleeve. The hub as to position is confined in the other direction-that is, the one in which it would crowd inwardly upon the axle-j ournalby means of .an abutment preferably combined with a ball-bearingwhich engages the outer end of the axle'and is carried by thc hub, within the recess at the outer end thereof. This ball-bearin g comprises, preferably, only one ball, as shown at 24, and is carried in a socket member 25, by which it is held within the recessed front end of the hub. This ballbearing consists of a perforated nut 26 and a cap 27, between which ball 24is supported, both being removably secured to socket 25 by means of a screw connection to permit independent renewal of these parts, as well as adjustment, as they wear and to maintain the proper relation between ball 24 and the end of the axle. Packing 2S may be interposed between these parts confining the ball.

Tear of the outer end of the axle-journal may be prevented and renewal of the worn parts provided for by interposing a screw, which may be attached to the end of the axlebearing and against the head of which ball 2- t bears. Socket member 25, with this ballbearing, as a whole is removably, as well as adjustably, secured within the outer open end of the hub by means of a screw connection. Openings to permit application of a spannerwrench are provided on all these parts. Unless the hub should be all metal it becomes necessary to provide a metal lining 29 for the recesses at the end of the hub, which by preference forms a part of or is connected to the end of box 9, and thus in a wooden hub serves to hold this latter in place. The outer parts of this ball-bearing, closing, as they do, the otherwise open recess in the front end of the hub, serve thus at the same time as a dustcap, excluding dirt and dust from the axlehearing and preventing escape of the lubricant. The same objects are accomplished at the inner end of the axle-bearing by suitable means-as, forinstance, bya packing-ring 31, which may be of rubber, and is held in tight contact with the axle by an open ring 32, encircling the same andv having a tendency to contract, thereby crowding the packingl constantly toward the bearing-surface. To permit the packingr to contract and follow this action, it is split by means of a suitable cut. For such purpose it may be cut, as shown at 33, 011 an inclined plane which starts on one side of it and passing entirely around it extends also through its entire thickness and comes out ou the other side thereof at a point diametrically opposite from the startingpoint. This split permits the packing to yield to the contracting action of ring 3G and to constantly close up around the axle as it is reduced by wear. To prevent it from rotating or slipping independently, I provide a pin 34: in the end of the hub, which engages a groove in the washer and which holds the same in one position without interfering with its contraction. The whole is contained within a recess formed in the rear or inner end of the hub similar to the recess in the front and closed by a nut 35.

The edges around the extreme outer and inner ends of the hub, if this latter is of wood, are protected by customary hub-bands, as shown.
